' CAR-AXLE Box.

SPECIFICATION forming part of Letters Patent No. 268,579, dated December 5, 1882.

- Application filed April 3,1882. (No model.)

citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Dust-Shields i'or Gar-Axle Boxes, of which the following is a specification, reference being bad therein to the accompanying drawings, wherein Figure 1 is an elevation of a dust-shield embod yin g myinvention,the car-axle being shown in section. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a detail end elevation, partly in section. Fig. 4 is a detail side elevation; and Fig. dis a broken section of car-axle and box with my improved shield applied thereto, the latter being shown in elevation. My invention has relation to dust-shields for car-axle boxes, and has for its object to providewa shield which will effectually exclude dust from the axle-box and prevent the oilin the latter leaking out thereof, such shield being so constructed that its wear is automatically taken up, thereby maintaining a tight joint between such shield and the car-axle.

My invention accordingly consists of the novel combination, construction, and arrangement of parts, as hereinafter specificallydescribed and claimed.

Referring to the accompanying drawings, A

represents a car-axle; B, the box, provided with recessed rear wall, as shown at b, Fig. 5, for the reception of dust-shield O. The latter is composed of two semicircular or other appropriately configured sections, D D, formed with lugs d d, which overlap each other when said sections'align with each other, as shown at d.

The sections D are hollow or formed with recesses D, in which is placed a packing of asbestus or other similar or suitable material, D E represents a metallic band passing around sections D to hold the latter in position. The.

' band E in close impingement with the sections D, and as the latter wear away the resilient action of the springs G causes the lower part of said band to approach the axle A, thereby au- The lower side, f, of cover F is shaped to conform to the outline of the adjacent section D, as shown.

I have described the packing D as being composed of asbestus, and such I prefer to use forthe reason thatit is incombustible. Hence, if at any time the Waste in the axle-box should take fire, such packing will not be burned or destroyed; but 1 do not limit myself to the use of such material, as any other suitable form of packing may be placed within the sections D D If desired, a layer of asbestus, D may be interposed between the wall I) and the sections D of the shield. Such asbestus, yielding to the inequalities of the metal wall I), more readily and effectually forms atight joint between said wall and sections. The layer of asbestus D" may be cemented or otherwise secured to sections D, as desired.

1 claim as my invention- 1. Adust-shieldtbrcar-axle boxes, com pose of two hollow metal sections, ineachi of which is placed a flexible or absorbent packing, the curved edges of which are flush with or pro ject beyond the curved edges of said. sections, a surrounding band, and springs, with retaining nuts"or pins secured to each end of said band for causing it to automatically take up the wear of said sections, substantially as IOC vided with a packing of asbestns material, springs H, substantially as shown and desubstantially as shown and described. scribed.
